Answer:
884 m
Explanation:
The motion of the baseball is a projectile motion: a uniform motion along the horizontal direction and a uniformly accelerated motion along the vertical direction.
The horizontal range of a projectile (the horizontal distance covered by the object before it reaches the original vertical height) is given by
where
u is the initial speed
is the angle of launch
g = 9.8 m/s^2 is the acceleration of gravity
For the ball in this problem,
u = 100 m/s
Substituting into the equation, we find the range of the ball:
so, the ball will cover 884 m before reaching the original vertical level.
Answer:
The correct option is "moving electric charges or currents".
Explanation:
Magnetic field is used to define as a field that surrounds a current carrying conductor or moving electric charge by virtue of which it exerts a force on another current carrying conductor or a moving charge itself.
The magnetic field generated by a moving charge is given by
where
q = is the magnitude of charge
v = is the velocity vector of the moving charge
r = is the position vector of the point at which the field is calculated
|r| = is the magnitude of position vector.
Similar the magnetic field generated by a current carrying conductor is given by
where
I is the current
The integration is carried out along the whole length of conductor.
Also since magnetic mono poles do not exist or their existence is not confirmed until now so it is not an appropriate option.
Answer:
a)
b)
c)
d)
Explanation:
a) We can find the electron's speed by knowing the kinetic energy:
Where:
K: is the kinetic energy = 1.59 keV
m: is the electron's mass = 9.11x10⁻³¹ kg
v: is the speed =?
b) The electron's speed can be found by using Lorentz's equation:
(1)
Where:
F: is the magnetic force
q: is the electron's charge = 1.6x10⁻¹⁹ C
θ: is the angle between the speed of the electron and the magnetic field = 90°
The magnetic force is also equal to:
(2)
By equating equation (2) with (1) and by solving for B, we have:
c) The circling frequency is:
Where:
T: is the period = 2π/ω
ω: is the angular speed = v/r
d) The period of the motion is:

Answer:
Relative to Carlos the Whataburger is moving at 0 speed.
Explanation:
Carlos speed, = 35 m/s
speed of another car, = -25 m/s
The speed of the Whataburger, = 35 m/s since it is in the same car as Carlos.
The relative of the Whataburger to Carlos is given as;
Therefore, Relative to Carlos the Whataburger is moving at 0 speed.
Biotic components are living things. The root word bio means life. When you say something is abiotic, it means non-living things. The prefix "a" means not or non.
<span>Sunlight and heat: Abiotic
Insects: Biotic
Rotting log: Biotic (This is considered biotic because it was a living thing.)
Bacteria: Biotic
Water: Abiotic
Rocks: Abiotic</span>
